The invention discloses a vehicle forward collision early warning method, device and equipment and a storage medium, and relates to the technical field of intelligent driving, and the vehicle forward collision early warning method comprises the steps: obtaining a plurality of frames of road environment feature images in front of a vehicle, and determining the position and speed information corresponding to an obstacle; according to a set safety distance, determining a suspected target with a potential threat; based on the position and the speed of the suspected target, calculating collision time corresponding to each frame of road environment feature image, and when the collision time calculated under a certain continuous frame number of road environment feature images is smaller than a set threshold value, marking the suspected target and the corresponding collision time; and selecting the suspected target with the collision time closest to the current time as a final target, and performing forward collision early warning by taking the collision time corresponding to the final target as the latest warning time. According to the method and the device, the probability of forward collision early warning false triggering caused by visual interference can be effectively reduced.
本发明公开了一种车辆前向碰撞预警方法、装置、设备及存储介质,涉及智能驾驶技术领域,车辆前向碰撞预警方法包括:获取多帧车辆前方的道路环境特征图像,确定障碍物对应的位置和速度信息;根据设定的安全距离,确定具有潜在威胁的疑似目标;基于疑似目标的位置和速度,计算每一帧道路环境特征图像对应的碰撞时间,当连续的一定帧数的道路环境特征图像下计算的碰撞时间均小于设定的阈值时,标记该疑似目标以及对应的碰撞时间;选择碰撞时间最接近当前时间的疑似目标作为最终目标,并将最终目标对应的碰撞时间作为最晚警告时间进行前向碰撞预警。本申请可有效降低因视觉干扰所带来的前向碰撞预警误触发的概率。
